摘要
采用参数化设计方法，可由计算机自动生成屋架有限元计算模型，并完成杆件的设计工作，其中关键技术是有限元单元的剖分方法。本文介绍了屋架参数化设计系统中一种单元剖分技术，并给出了计算实例。
Adopting the parameterized designing method,the finite element analysis for roof truss and the design of bars can be derived automaticly by computer.the key skill is the dividingmethod for finite elements.One of tile element dividing techniquein the system of parameter designing for roof truss was introduced.and an example was given.
